Sorry I didn't remember your Dad's name, know he was instrumental in the cars, maybe drove a bracket Daytona they built as well? In any case I knew Ralph did nice work based on Tank's rides but had no idea he helped build your cars. My best to Jerry and your Dad...here is a link to one of my albums, sure they will remember the Dusters and the 63 Plymouth (an ex-Tim Wilkerson ride no less).
